regarding the implementation of the bcc idea, it would be nice to be able to actually verifiy in your sent message who the recipients were (1-several bcc's).

another service, but thats just luxury, would be if you could see wwho you'd sent your message to immediately after submitting it, like this: ‘This messages has been sent to Florence, Venice and Milan’.

Cranocide, regarding the first suggestion, it's a bit difficult, since each bcc is saved as a separate message in the database. Nonetheless, you have one message in your outbox for every bcc that you sent.
